Be it known that I,'FR.-\N K P. Miss, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain'new and useful Improvements in Fan Structures, of which the following is a specification.

My invention elates to systems and apparatus for ventila ing, heating, and cleaning, and has especial reference to systems of this character wherein fans or the like are em ployed to produce more or less pressure or attenuation of the air or atmosphere as required for accomplishing the desired results.

The object of my invention is to apply and use the apparatus of the character usually employed separately for ventilating, heating, and cleaning in a single system, and by so arranging and adjusting said apparatus as to adapt it to perform all. of these effects conveniently and economically.

A further object of my invention is to improve generally and specifically the apparatus required for these purposes and to a-r-' range and associate said devices in cooperative relation, so that they may readily be adapted to perform the several functions for which they are respectively designed, without change of relative location.

Other and further objects ofmy invention will become apparent to persons skilled in the art to which it appertains.

In the drawings, I have illustrated an embodiment of my invention, wherein- Figure 1 is a plan View of the apparatus showing the various devices in operative relation and mounted on a single base; Fig. 2 is an enlarged longitudinal section taken on line 22 of Fig. 1; Fig. 3 is a similar view taken on line 3-3 ofFig. 1; Fig. 4 is a cross-sectional view looking toward the top taken on line 4-4 of 3; Fig. 5 is a longitudinal section taken on line of Fig. 1; Fig. 6 is a sectional View taken on line '6-6 of Fig. 5; Fig. 7 'is an end view showing a part of the base in section taken on line 77 of Fig. 1; Fig. 8 is a fragment of the assembled parts shown in Fig. 15; Figs. 9, 10, and 11, are sectional views taken on line 9 9 of Fig. 15, showing the air intake valve in its various positions; Fig. 12 is an elevation of a hose attachment, shown in dotted lines in Fig. 15; Fig. 13 is an enlarged sectional view taken on line 13-13 of Fig. 15; Fig. 14 is a sectional View taken on tional plan view showing a schematic arrangement of the devices to carry my system into effective operation.

In all of the views the same reference characters indicate similar parts.

A fan casing, indicated generally by 25, is composed of a lower part, 26, and an upper arch-shaped part, 27, within which the fan, 28, is rotated and has bearing supports. The intake of the fan is near its axis. The

part 26is provided with two discharge outlets, 29 and 30. Midway between these out lets and in the same vertical plane with the aXis of the fan is a projection, 31. The fan chamber, proper, 34, is adapted to be entirely cut off from either of the chambers, 32and 33, by the valve The valve 35 is shown, in Fig. 2, bridging the points 31 and 36, thereby closing communication between the chambers 32 and 34. When the valve is caused to bridge the points 37 and 31, communication between chambers 33 and 34-is thereby closed. The valve 35 is supported by a part, 38 having arm's, 3838 which have pivotal support around the fan shaft, 28. An arm, 39, ,is also pivoted on the shaft 28' and is located without the casing 27. The end 40 is connected, through a slot 41 (Fig. 7) by means of a bolt, 42, with the valve support, 38. The other end, 39*, of the oscillating arm, 39, is circumferentially slotted as at 43. It has pivotal connection with a current-reversing electric switch, 44, by means of a link, 45. When the arm 39 is moved to dotted-line position the' switch is coincidently opened and then closed by such movement, more clearly shown in the schematic view, Fig. 15.

In practically the same exterior casing (see Figs. 3 and 4) air chambers, 46 and 47, are contained. These chambers are surrounded by'walls, 48, and are divided by a wall, 49, and a communicating valve, 50. Walls, 51 and 51, with the arched connecting wall, 52, separate the chambers 46 and 47 from the chamber 53. The valve 50 and its housing 52 are preferably truncated coneshape, the larger end of which communicates with the fan casing 34 at the axis .of the fan and the smaller end is opened to the atmosphere and may be closed by the damper, 53. The valve 50 is shown in position (in Figs. 3 and 9) to close communication between the eye of the fan and chamber 46. When the.

valve is turned to. osition to bridge the walls '51- and 49 (Fig. 10) communication will .be thereby closed between chamber, 47 and the eye of the fan and the opening between chamber 46 and the fan established. The valve'may be rotated in the manner described by means of the forked project-ioh 54. When the damper 53 is raised, as shown in Fig. 13, a hose 55, having a suitable head, 56, may. be inserted within the forks of the extension and the hose is thusbrought into communication with the eye of the fan.

When the valve 50 is turned farther (Fig.

11) until its lower' edge is just in touch with the wall 51, both chambers 46 and 47 are shut oif from communication with the fan and air may be taken through the hose 55. A removable casing 56 has removable con nection with the fan exhaust outlets 29 and and may be held in place by meansof the screw-threaded ring, 57. 'The casing, 56, (Fig. 5) is divided into two chambers, 58 and 59, in either or both of which may be contained a heating or cooling medium for heating or cooling the air as may be desired.

Inthe drawings, I have-shownan electric heater, 60, connected to wires w-y-by wires- 60 -460", and which forms the subject matter for another application filedon even date From the fan, air enters the casing, 56, at 61, rises in chamber '58, then passes downwardly through and over the heater 60 in the mixing chamber, 59, and out through the swivel elbow, 62.. To give the heated air an upward path the elbow 62 may be turned as shown by dotted lines in Fig. 5. Should the airbe cooled by any suitable refrigerating means the heater 60 may be replaced by such a means or device, and the air may be direct ed downwardly by the elbow 62 when turned as shown in full'lines.

In Fig. 12, I have shown a meanswhereby either of the ends or openings, 3233, of the fan chamber may be closed, as by means of a screw-threaded disk -63, and a hose 64 thereby connected to any of said screw- V threaded openings. An electric motor, 65, is

directly connected tothe fan-shaft, 28', to give rotary movement to said fan, said motor being connected to service mains, A B,

through wires to .and y and a motor-reversin switch,44. An air strainer, 66, consisting o e a bag of suitable reticulated material may be connected to the elbow, 62, and the latter connected to one of the fan casing or air chamber openings, as shown in Fig. 15, for purposes to be hereinafter described.

The apparatus, as shown, in Fig. 15, may be mounted on a common base 67, and the device may be provided with a vertical end board, 68, and placed within a window and the sash, 69 (Figs. 2 and 3) can be closed fresh cool air down on said board whereby may be taken from the exterlor or dust from follows: When the device is to be used for warming the apartment by taking air from the exterior of the room; the valve 35 is turned as shown in'Fig. 2; the valve 50 is turned as shown in Fig. 10; at the same time that the valve 35 is moved into this position, by the arm 39, the switch, 44, is thereby closed in such manner as to cause the electric motor to turn the fan anti-clockwise, as viewed in Fig. 2; air, therefore, will be taken into chamber 46, through opening 46 from the exterior; it will be drawn therefrom through the open port of valve 50 into the eye of the fan, thence projected into the chamber 33' through the opening 30 into chamber 58 (Fig. 5), thence through the heater 6'0; thence through the chamber 59, and given an upward turn by the elbow 62. When the switch is closed in this manner to cause the motor to turn in the proper direction, the circuit thereby may be coincidently closed through the electric heater. desirable to simply reheat the air within the apartment, the device may be removed from the window and the air from the apartment will enter the opening 46 instead of taking cold air from without the. apartment, as. in the previous example. When it is desirable to reheat the air in the room and to take air also from outside of the room, the device 50 may be turned so that the port may be opened into both the chambers, 46 and 47, the openings to the respective chambers being varied in extent to vary the relative pro; portions of warm and cold air, in a manner clearly apparent. 7

When it is desirable to use the apparatus for cleaning purposes, the valve 50 may be turned into position, as shown in Fig. 9, and the valve 35 should be turned so as to bridge the gap between 31 and 37, and thereby close communication between the fan chamber proper and the chamber 33, at the same time the reversing switch is operated so as to reverse the direction of the motor to turn the fan clockwise. Air may then be taken from the room through the opening 47; through the valve port of valve 50 into'the eye of the fan and exhausted outside of the room through opening 29. Instead of exhausting outside of the room the elbow, 62, and bag, 66, may be attached to the screw-threaded end surrounding the opening, 29, andthe hose, 64, with nozzle, 55; and cap 63 may be placed over the opening 47 F and thereby dust maybe taken'from carpets, rugs, and other furnishings, and exhausted outside of the room or into the dust receiving bag, 66, as desired. The hose and cap may be placed on the end 29 and air may be thereby forcibly projected through the hose to stir up The use and operation of the system are as If it is shown in Figs. 13 and 15, and the dustladen air taken directly through the coneshaped hollow valve, 50, and exhausted into the bag, 66, from whence only purified air will escape and wherein the dust will be retained or the dust andair may be exhausted into the outside atmosphere. NVhen it isrnot desirable to use the casing, 56, containing the heating or cooling medium, it may be readily detached and removed. 4

While I have herein described my invention in some detail, it will be apparent that many changesB ight be made from the par ticular 'constru ion and arrangement above described without departure from the spirit of my invention and within the scope of the following claims.

having tangential outlets and an axial inlet and providing also a co-extensiveinlet chamber divided into two compartments, said axial inlet communicating with said compartments, and valves for closure of either inlet compartment or either outlet to the exclusion of the other.

3. In a device of the character described, a fan, a casing providing a fan chamber having an axial inlet and an inlet chamber coextensive with the'fan chamber and divided into two compartments each communicating with said inlet to the fan chamber, and a conical valve closing communication between the axial inlet and both of said compartments or either thereof to the exclusion of p the other, the end of said conical valve havtwo outlets, a valve for closing either thereof, and means to operate said valve coincidently with reversal of rotation of the motor comprising'a reversing switch for the motor and an arm, pivoted on said shaft, having connection respectively with said switch and valve for movement of the valve upon movement of the switch from one position to another.

5. In a device of the character described,

a fan inlet chamber having a conical valve seat, a conical valve having an'open end, and a projection upon saidend of the conical valve to receive a hose, a closure, or. for turning said valve, as described.

In testimony whereof I hereunto set my hand in the presence of two witnesses.
